| 6.1.5 | Flowchart of the ACL test matching process

By matching the first test, a packet is denied access to the destination. It is discarded and dropped into the bit bucket, and it is not exposed to any ACL tests that follow. If the packet does not match conditions of the first test, it drops to the next statement in the ACL. ACLs allow you to control what clients can access on your network. Conditions in an ACL file can: Screen certain hosts to either allow or deny access to part of your network Grant or deny users permission to access only certain types of files, such as FTP or HTTP.
